Gunningite is one of the minerals in the Kieserite group. Its chemical formula is (Zn,Mn2+)SO4·H2O. Its name honours Henry Cecil Gunning (1901–1991) of the Geological Survey of Canada and a Professor at the University of British Columbia, Vancouver, British Columbia, Canada.
Occurrence
Gunningite is rare. It is found in dry areas of the oxidized portions of sphalerite-bearing deposits. It has been noted in mines in Canada (Yukon Territory, British Columbia and New Brunswick), the United States (Nevada and Arizona), Switzerland (Valais), Greece, Attica and Germany (Baden-Württemberg).
